High Purity Xinlisitaka Raw Material CAS Number: 282526-98-1

Xinlisitaka is a reversible gastrointestinal lipase inhibitor with a mechanism of action similar to orlistat. It mainly works locally in the digestive tract, inhibiting the activity of gastric lipase and pancreatic lipase, hindering the breakdown and absorption of dietary triglycerides, reducing fat intake, and achieving weight control; Compared to orlistat, some clinical studies suggest that the adverse reactions of gastrointestinal oil excretion are relatively milder.

As a research grade weight reducing active raw material, Xinlishi has a complete and rigorous purity system and quality control standards. It follows the pharmacopoeia general rules and ICH quality control guidance principles throughout the process, from raw material synthesis, refining and purification to finished product outbound, ensuring stable indicators, purity standards, and controllable impurities for each batch of products. It is suitable for various scientific research experiments, testing and development, and formula debugging scenarios. The mainstream purity of this product is divided into two levels. The purity of conventional refined raw materials is ≥ 98.0% (HPLC liquid phase detection), and the purity of high-purity refined raw materials can reach over 99.0%. The purity of high-quality products is stably maintained at 99.5%. All purity data are accurately detected by high-performance liquid chromatography area normalization method. The linearity, separation degree, and tailing factor all meet the system applicability requirements, and the detection data is true and traceable.
In terms of impurity control, our company implements strict internal control standards to strictly control various organic and inorganic impurities. The limit of a single unknown impurity is ≤ 0.10%, and the process related impurities are strictly controlled. The total impurity content is ≤ 0.5%, effectively avoiding the accumulation of impurities that may affect experimental data and product stability. At the same time, strictly control the drying weight loss index, control it to ≤ 0.5%, and prevent the raw materials from absorbing moisture and lowering the effective content due to excessive moisture content; Burning residue ≤ 0.1%, strictly control inorganic impurities such as inorganic salts and metal residues. The total content of heavy metals is strictly controlled within 10ppm, which meets the safety and quality control requirements of scientific research raw materials and eliminates the problem of excessive heavy metals.
The complete set of quality control testing items is standardized and includes core indicators such as appearance, melting point identification, purity content, related substances, moisture drying loss, ignition residue, heavy metals, solubility, and crystal consistency. Each batch of products can be issued with a formal COA quality inspection report. HPLC-DAD is used as the core quantitative method for detection, combined with LC-MS/MS for impurity qualitative confirmation, to accurately identify trace unknown impurities and ensure the accuracy and reliability of detection results. The raw materials are strictly sealed in the dark and stored in a low-temperature dry manner, effectively avoiding degradation and deterioration caused by high temperature, light, and humidity, and eliminating the problems of purity degradation and impurity increase. All batches have uniform quality, small batch differences, stable and controllable quality, fully meeting the high standard usage requirements for scientific research experiments, analysis and testing, and formula development.
